You mean they pre-sort the arguments the way they want?

Sure, you could do that. Though if it were me, I'd probably just re-write
the test myself.

But throughout all this -- I haven't thought of a single case where I would
prefer a symmetric test and it would matter.

It certainly appeals to me as clean, and more similar to equal, etc, but I
haven't come up with a practical reason to prefer it.

Can anyone?
